Nolan Ryan remains hospitalized after undergoing tests on his heart

Former Astros pitcher and Texas Rangers CEO Nolan Ryan underwent a series of tests Monday in Houston after being hospitalized for a heart condition.

According to a statement from Major League Baseball, Ryan, 64, likely will be released in a day or two after what was believed to be a recurrence of a heart condition he previously suffered.

Ryan experienced discomfort early Sunday morning at his home in Georgetown.

According to Ryan’s friend and business partner Don Sanders, who has been in touch with the family, Ryan felt good Monday morning before the tests began.

“Bottom line is he hasn’t felt real well the last couple of weeks; he just had a couple of episodes,” said Sanders, a Houston-based investment manager who with his family co-owns the Class AA Corpus Christi Hooks and Class AAA Round Rock Express with the Ryan family. “I think these things are scary more than anything else.”

Ryan had a double-bypass operation in April 2000. Doctors said at the time that he had not suffered a heart attack.

About six months after the procedure, Ryan was hospitalized for a few days after complaining of chest pains.

Ryan, born in Refugio and raised in Alvin, is a Baseball Hall of Famer who holds the major league records for career no-hitters (seven) and strikeouts (5,714).

He’s been running the Rangers since 2008 and became part-owner last summer as Texas was on its way to the World Series for the first time.

Ryan pitched for the Astros from 1980-88, leading the National League twice in ERA and twice in strikeouts during that period.
